Abstract

The continued use of vast amounts of gravel in maintenance of low volume traffic roads does not only depletes it, but also is un-sustainable in the medium to long term run compared to bituminous sealing of them using low cost materials. One of the materials required to achieve the later are chippings. In Uganda, Only few kilometers of these roads can be sealed in a financial year due to low indicative planning figures for road maintenance and this makes hand crushing of the chippings possible as only a small quantity will be required. This leads to employment creation and protecting the environment from noise and dust pollution caused by machine blasting. Haulage distances for these chippings from the quarries to sites of application also impact considerably the cost of these low cost sealing projects. It’s against the above background that hand crushed samples from Akia and Ngeta quarries were taken and analyzed for their suitability as surfacing materials for single surface dressing of low volume traffic roads. All the parameters analyzed were within the permissible limits.
